I just have a quick question about Crossfiring. And before you ask, yes I have Googled this, but the results I came up with were conflicting and unclear. I just want a straightforward answer. I have a HIS IceQ HD 6950 with 1 GB of memory in my computer right now. I want to know if I can crossfire with a different brand and a card with 2 GB of memory. From my understanding, this will work, but again, I just want to be sure before I spend the money.
